of
FTP protocol.</p>
<p>This class provides a direct interface to FTP that allows you to
have more control over the requests. However, for new applications,
it is recommended to use <a href="qnetworkaccessmanager.html">QNetworkAccessManager</a> and <a href="qnetworkreply.html">QNetworkReply</a>, as those classes possess a
simpler, yet more powerful API.</p>
<p>The class works asynchronously, so there are no blocking
functions. If an operation cannot be executed immediately, the
function will still return straight away and the operation will be
scheduled for later execution. The results of scheduled operations
are reported via signals. This approach depends on the event loop
being in operation.</p>
<p>The operations that can be scheduled (they are called "commands"
in the rest of the documentation) are the following: <a href="qftp.html#connectToHost">connectToHost</a>(), <a href="qftp.html#login">login</a>(), <a href="qftp.html#close">close</a>(), <a href="qftp.html#list">list</a>(),
<a href="qftp.html#cd">cd</a>(), <a href="qftp.html#get">get</a>(),
<a href="qftp.html#put">put</a>(), <a href="qftp.html#remove">remove</a>(), <a href="qftp.html#mkdir">mkdir</a>(), <a href="qftp.html#rmdir">rmdir</a>(), <a href="qftp.html#rename">rename</a>() and <a href="qftp.html#rawCommand">rawCommand</a>().</p>
<p>All of these commands return a unique identifier that allows you
to keep track of the command that is currently being executed. When
the execution of a command starts, the <a href="qftp.html#commandStarted">commandStarted</a>() signal with the
command's identifier is emitted. When the command is finished, the
<a href="qftp.html#commandFinished">commandFinished</a>() signal is
emitted with the command's identifier and a bool that indicates
whether the command finished with an error.</p>
<p>In some cases, you might want to execute a sequence of commands,
e.g. if you want to connect and login to a FTP server. This is
simply achieved:</p>
<pre class="cpp">
 <span class="type">QFtp</span> <span class="operator">*</span>ftp <span class="operator">=</span> <span class="keyword">new</span> <span class="type">QFtp</span>(parent);
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#connectToHost">connectToHost</a>(<span class="string">"ftp.qt.nokia.com"</span>);
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#login">login</a>();
</pre>
<p>In this case two FTP commands have been scheduled. When the last
scheduled command has finished, a <a href="qftp.html#done">done</a>() signal is emitted with a bool argument
that tells you whether the sequence finished with an error.</p>
<p>If an error occurs during the execution of one of the commands
in a sequence of commands, all the pending commands (i.e.
scheduled, but not yet executed commands) are cleared and no
signals are emitted for them.</p>
<p>Some commands, e.g. <a href="qftp.html#list">list</a>(), emit
additional signals to report their results.</p>
<p>Example: If you want to download the INSTALL file from the Qt
FTP server, you would write this:</p>
<pre class="cpp">
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#connectToHost">connectToHost</a>(<span class="string">"ftp.qt.nokia.com"</span>);   <span class="comment">// id == 1</span>
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#login">login</a>();                             <span class="comment">// id == 2</span>
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#cd">cd</a>(<span class="string">"qt"</span>);                            <span class="comment">// id == 3</span>
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#get">get</a>(<span class="string">"INSTALL"</span>);                      <span class="comment">// id == 4</span>
 ftp<span class="operator">-</span><span class="operator">&gt;</span><a href="qftp.html#close">close</a>();                             <span class="comment">// id == 5</span>
</pre>
<p>For this example the following sequence of signals is emitted
(with small variations, depending on network traffic, etc.):</p>
<pre class="cpp">
 start(<span class="number">1</span>)
 <a href="qftp.html#stateChanged">stateChanged</a>(HostLookup)
 <a href="qftp.html#stateChanged">stateChanged</a>(Connecting)
 <a href="qftp.html#stateChanged">stateChanged</a>(Connected)
 finished(<span class="number">1</span><span class="operator">,</span> <span class="keyword">false</span>)

 start(<span class="number">2</span>)
 <a href="qftp.html#stateChanged">stateChanged</a>(LoggedIn)
 finished(<span class="number">2</span><span class="operator">,</span> <span class="keyword">false</span>)

 start(<span class="number">3</span>)
 finished(<span class="number">3</span><span class="operator">,</span> <span class="keyword">false</span>)

 start(<span class="number">4</span>)
 <a href="qftp.html#dataTransferProgress">dataTransferProgress</a>(<span class="number">0</span><span class="operator">,</span> <span class="number">3798</span>)
 <a href="qftp.html#dataTransferProgress">dataTransferProgress</a>(<span class="number">2896</span><span class="operator">,</span> <span class="number">3798</span>)
 <a href="qftp.html#readyRead">readyRead</a>()
 <a href="qftp.html#dataTransferProgress">dataTransferProgress</a>(<span class="number">3798</span><span class="operator">,</span> <span class="number">3798</span>)
 <a href="qftp.html#readyRead">readyRead</a>()
 finished(<span class="number">4</span><span class="operator">,</span> <span class="keyword">false</span>)

 start(<span class="number">5</span>)
 <a href="qftp.html#stateChanged">stateChanged</a>(Closing)
 <a href="qftp.html#stateChanged">stateChanged</a>(Unconnected)
 finished(<span class="number">5</span><span class="operator">,</span> <span class="keyword">false</span>)

 <a href="qftp.html#done">done</a>(<span class="keyword">false</span>)
</pre>
<p>The <a href="qftp.html#dataTransferProgress">dataTransferProgress</a>() signal
in the above example is useful if you want to show a <a href="qprogressbar.html">progress bar</a> to inform the user about the
progress of the download. The <a href="qftp.html#readyRead">readyRead</a>() signal tells you that there
is data ready to be read. The amount of data can be queried then
with the <a href="qftp.html#bytesAvailable">bytesAvailable</a>()
function and it can be read with the <a href="qftp.html#read">read</a>() or <a href="qftp.html#readAll">readAll</a>() function.</p>
<p>If the login fails for the above example, the signals would look
like this:</p>
<pre class="cpp">
 start(<span class="number">1</span>)
 <a href="qftp.html#stateChanged">stateChanged</a>(HostLookup)
 <a href="qftp.html#stateChanged">stateChanged</a>(Connecting)
 <a href="qftp.html#stateChanged">stateChanged</a>(Connected)
 finished(<span class="number">1</span><span class="operator">,</span> <span class="keyword">false</span>)

 start(<span class="number">2</span>)
 finished(<span class="number">2</span><span class="operator">,</span> <span class="keyword">true</span>)

 <a href="qftp.html#done">done</a>(<span class="keyword">true</span>)
</pre>
<p>You can then get details about the error with the <a href="qftp.html#error">error</a>() and <a href="qftp.html#errorString">errorString</a>() functions.</p>
<p>For file transfer, QFtp can use both active or passive mode, and
it uses passive file transfer mode by default; see the
documentation for <a href="qftp.html#setTransferMode">setTransferMode</a>() for more details
about this.</p>
<p>Call <a href="qftp.html#setProxy">setProxy</a>() to make QFtp
connect via an FTP proxy server.</p>
<p>The functions <a href="qftp.html#currentId">currentId</a>() and
<a href="qftp.html#currentCommand">currentCommand</a>() provide
more information about the currently executing command.</p>
<p>The functions <a href="qftp.html#hasPendingCommands">hasPendingCommands</a>() and
<a href="qftp.html#clearPendingCommands">clearPendingCommands</a>()
allow you to query and clear the list of pending commands.</p>
<p>If you are an experienced network programmer and want to have
complete control you can use <a href="qftp.html#rawCommand">rawCommand</a>() to execute arbitrary FTP
commands.</p>
<p><b>Warning:</b> The current version of QFtp doesn't fully
support non-Unix FTP servers.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Command-enum" />QFtp.Command</h3><p>This enum is used as the return value for the <a href="qftp.html#currentCommand">currentCommand</a>() function. This
allows you to perform specific actions for particular commands,
e.g. in a FTP client, you might want to clear the directory view
when a <a href="qftp.html#list">list</a>() command is started; in
this case you can simply check in the slot connected to the start()
signal if the <a href="qftp.html#currentCommand">currentCommand</a>() is

<a href="qftp.html#commandStarted">commandStarted</a>() signal has
been emitted, but for which the <a href="qftp.html#commandFinished">commandFinished</a>() signal has not
been emitted), this function sends an <tt>ABORT</tt> command to the
server. When the server replies that the command is aborted, the
<a href="qftp.html#commandFinished">commandFinished</a>() signal
with the <tt>error</tt> argument set to <tt>true</tt> is emitted
for the command. Due to timing issues, it is possible that the
command had already finished before the abort request reached the
server, in which case, the <a href="qftp.html#commandFinished">commandFinished</a>() signal is emitted
with the <tt>error</tt> argument set to <tt>false</tt>.</p>
<p>For all other commands that are affected by the abort(), no
signals are emitted.</p>
<p>If you don't start further FTP commands directly after the
abort(), there won't be any scheduled commands and the <a href="qftp.html#done">done</a>() signal is emitted.</p>
<p><b>Warning:</b> Some FTP servers, for example the BSD FTP daemon
(version 0.3), wrongly return a positive reply even when an abort
has occurred. For these servers the <a href="qftp.html#commandFinished">commandFinished</a>() signal has its
error flag set to <tt>false</tt>, even though the command did not
complete successfully.</p>

one of the <a href="qftp.html#State-enum">State</a> values.</p>
<p>It is usually emitted in response to a <a href="qftp.html#connectToHost">connectToHost</a>() or <a href="qftp.html#close">close</a>() command, but it can also be emitted
"spontaneously", e.g. when the server closes the connection
unexpectedly.</p>
